Determining module, for determining whether airborne vehicle passes through target waypoint according to the comparative result of second comparison module.
8. device according to claim 7, it is characterised in that the determining module includes the first determining unit, and second is true
Order member and the 3rd determining unit;
If the preceding air route section that first comparison module compares target waypoint is longer, when second comparison module compares
Go out first apart from when being less than second distance, trigger first determining unit;
First determining unit, for determining airborne vehicle without target waypoint;
When second comparison module, which compares the first distance, is equal to second distance, second determining unit is triggered;
Second determining unit, for determining that airborne vehicle passes by target waypoint;
When second comparison module, which compares the first distance, is more than second distance, the 3rd determining unit is triggered;
3rd determining unit, for determining that airborne vehicle has been subjected to target waypoint.
9. device according to claim 7, it is characterised in that the determining module includes the first determining unit, and second is true
Order member and the 3rd determining unit;
If the rear air route section that first comparison module compares target waypoint is longer, when second comparison module compares
Go out first apart from when being more than second distance, trigger first determining unit;
First determining unit, for determining airborne vehicle without target waypoint;
When second comparison module, which compares the first distance, is equal to second distance, second determining unit is triggered;
Second determining unit, for determining that airborne vehicle passes by target waypoint;
When second comparison module, which compares the first distance, is less than second distance, the 3rd determining unit is triggered;
3rd determining unit, for determining that airborne vehicle has been subjected to target waypoint.
10. device according to claim 8 or claim 9, it is characterised in that also include:Second setup module and computing module;
Second setup module, for setting normal line, the normal line passes through target waypoint, and with the standard point and
The line of shorter another end points of air route section is vertical;
The computing module, for according to airborne vehicle in position P1When the radar time, airborne vehicle is in position P2When radar when
Between, P1To the vertical range and P of normal line2To the vertical range of normal line, time of the airborne vehicle Jing Guo target waypoint is calculated,
Wherein, P1It is airborne vehicle without position during target waypoint, P2The position for being airborne vehicle after target waypoint.
